Actually, joking aside. I have on the bench a Trio(Kenwood) JR310 which has
a very (?) stable VFO which might be further improved by "huff & puff"
stabilisation (already discussed with G3nyk). The VFO is solid state but
otherwise it is all "fluid technology" (in the sense that inter-electrode spaces
are not solid) and seems remarkably "bombproof" in the presence of strong
signals. It seems ripe for having LF added if image and other probs can be
circumvented. I wonder if group members would care to comment.
